Documented User Cases
Case 1: Rubber Hose Manufacturer (Thailand)
- Challenge: Inconsistent vulcanization rates causing 12% production waste
- Solution: 0.8-1.2% SDEDC addition in rubber compound
- Outcome: 18% faster production cycle, waste reduced to 3.2%
Case 2: Municipal Wastewater Plant (China)
- Problem: Excessive copper levels (2.8 ppm) in discharge water
- Implementation: 150 ppm SDEDC dosage in tertiary treatment
- Result: Cu²⁺ levels reduced to 0.3 ppm, meeting Class I discharge standards
